Input: exc3000 - add support to query model and fw_version
Expose model and fw_version via sysfs. Also query the model in probe to make sure, that the I2C communication with the device works before successfully probing the driver. This is a bit complicated, since EETI devices do not have a sync interface. Sending the commands and directly reading does not work. Sending the command and waiting for some time is also not an option, since there might be touch events in the mean time. Last but not least we do not cache the results, since this interface can be used to check the I2C communication is still working as expected.
